Machine used to reproduce the effect of riddling in the production of sparkling wines. Bottles held in a cage are gradually moved to the upright position, shaking the sediment of dead yeast cells into the neck. The girasol achieves this in a few days, compared with several weeks for manual riddling.

Technique of joining fruit-bearing vines (usually Vitis vinifera) to rootstocks, usually of other Vitis species. Since the outbreak of phylloxera in the nineteenth century, most of the world's vineyards have been planted with vinifera vines grafted onto rootstock of vines native to America, which are resistant to phylloxera. Different rootstocks are chosen to suit soil type and to manipulate yield and vigor.

Literally '(classified) great growth'. The meaning varies by region. Within Bordeaux, grand cru class refers to the top estates of Medoc, Graves and Sauternes, and the top wines of St Emilion. In Burgundy and Chablis the very top vineyard sites are referred to as grands crus (which is a higher classification than premier cru). Alsace also has vineyards classified as grands crus (fairly recently), and in Champagne this designation is used for the most highly rated vineyard sites (and by extension the wines made exclusively from them).
